I was driving my 97 k1500 about 15mph and I hit a somewhat bump not really big. And my truck made a large pop and I didn't have any power at all at the wheels and it makes a ticking noise when I put it in any gear and the rpm goes from about 750 to 1500 and the truck wont move it just makes a thumping noise I checked my tranny levels I was pretty much out so I put some more in and still nothing. I did some research and it said something that possible my joints on my rear shafts went out. I wouldn't think the new tranny with less than 10k on it would just randomly out by hitting a bump with low fluid would cause this and my tranny temp runs at a normal level. really would like some input from you guys as my truck sits at the local high school
